Informal Testing Suggests Minor Performance Increase for iPhone 3G on iOS 4.1

It looks like more than a "minor performance" gain to me.

It is a big enough difference to upgrade. I had downgraded from 4.0 to 3.1.3 due to the really poor performance. 4.1 does kick it up a significant notch and I would say that the improvements I've seen are better than those posted here.

it'd be better to have a video of iPhone 3G running 3.1.3 vs running 4.1 :-)

also, run the bench multiple times, in order to have an accurate benchmark.

i tried 4.0 on a 3G and it was painful.

This "minor difference" is enough to make one not throw the phone against the wall.

Always nice to see.

I went to the 5th Av store today to begin the documentation process of getting a Genius to file a case on my 3G, and trying to get a break on something to encourage me to buy an iPhone 4.

Obviously we were misled into upgrading to 4.0 on a 3G. Apple only stated that certain features were not going to be available for 3G users, but never said that performance would create a severe usability problem—so much so that it deserves a class-action suit for lack of accountability for AppleCare-covered devices that thus cannot be used properly, as sold and warranted.

I got nowhere with the Genius or the manager, but figured as much anyway.

What really struck me as odd is that the manager of the flagship NYC store said that a program on apple.com was available at some point to downgrade to 3.X, but was recently removed in light of the impending 4.1 release. I said I had never heard of any Apple-sanctioned method, and certainly would have here on MR. They searched for it on several Apple sites, both inter- and intranet, but couldn't find what he was talking about.

Has anyone heard of this? I Googled and only came up with the variety of step-by-step methods many of you have used, which require a jailbrake of some form, correct?

Just thought I'd share this. I am really pissed that Apple has forced our hand to renew a contract we may not have wished to with AT&T, and made a handicapped iPod out of a perfectly good iPhone when running 3.x, and then purchasing an iPhone 4.

Conspiracy theorists (and lawyers) can jump hard on Apple for essentially creating obsolescence.

I'd rather Apple give me a supported way of downgrading from iOS 4.0.2 to iOS 3.x on my 3G, since many feaures of the current and next iOS are unavailable to me.

It would be interesting to see a performance comparison between iOS 4.1 and iOS 3.1.3 on the iPhone 3G.

It could turn out that keeping iOS 3 is still better, after all.

Generally for a side-by-side comparison, they have to be doing the same things.

Just saying.

If I stil had my 3G and upgraded to 4.0....then I wouldn't of had my 3G much longer because it would have been out the window.
I can only imagine how frustrated some 3G owners must be. Might even be enough to drive some people away from the iPhone.
